**How it works ?**

- In the applet below, the perpendicular bisector of the blue segment (with endpoints
*A*and*B)*is shown. - Before completing the directions below, move/drag points
*A*and*B*around to verify that the brown line is the perpendicular bisector of*AB*. -
**Directions: Use the tools of GeoGebra to do the following:** - 1) Plot a point anywhere
this perpendicular bisector.*on* - 2) Measure and display the distance from this point to point
*A*. 3) Measure and display the distance from this point to point*B*. - 3) Now drag this point along the perpendicular bisector as much as you’d like. Be sure to zoom out and keep dragging this point along this perpendicular bisector.
*What do you notice?*- 4) Use your observations to complete the following statement:
**If a point lies on the ______________________ ___________________ of a ________________________, then that ____________ is ___________________ from the ____________________ of that _____________________.**
